Hi Merlin,
Welcome and I'm glad you found us.
Yes, I understand the isolation. By the time I stopped drinking, my life had become very small.
What's next, I think, is to talk to your dr and find out if it's safe for you to stop drinking. Hopefully it is and you can get through the day without alcohol. What worked for me in the early days, was changing my routines and daily patterns. I had to plan to be doing something different at the times when I would have been drinking.
Try to not be overwhelmed by your situation. Just get through each day and begin to move forward.
It's good things are going well at work. And, I'm very glad you have arranged counselling.
